Method for determining proportion of anti-mud concrete
The invention belongs to the technical field of concrete preparation, and discloses a method for determining the proportion of anti-mud concrete, which comprises the following steps: detecting the mud content of different sandstone aggregates, and quantitatively analyzing the contents of main clay minerals such as montmorillonite, kaolin and illite; detecting the adsorption capacity of different sandstone aggregates to the polycarboxylic acid water reducing agent; the adsorption rule is used for determining the optimal concrete formula according to the influence of the gravel aggregate on the adsorption characteristic of the polycarboxylic acid water reducer under the conditions of the chain length, the branch chain length and the pH value of the polycarboxylic acid water reducer, the environmental salinity, the salt type and the like. According to the invention, the adsorption theory and research results of the existing clay mineral components on the polycarboxylic acid water reducing agent are applied to actual production, the adsorption characteristic of the gravel aggregate on the polycarboxylic acid water reducing agent is determined, and the method has important significance for adjusting and determining an optimal concrete formula and exploring mud-resistant ways and measures with high cost performance. And the method has important theoretical significance and practical application value in guaranteeing the workability and slump retention capacity of fresh concrete and the strength and durability of the concrete.
